SPECIFICATION forming part of'Letters Patent No. 7eo,ee5, dated. May 24, 1.904. M A I Application filed May 27, 1903. Serial No. 158,949. (No model.) i

T at whom it may concern:

Be it known that I, J oHN H. VIN'roN, a citizen of the United-States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Imi the following is a specification.

Thisinvention relates to calks for horseshoes, the object of the invention being to provide a calk which can be readily attached to a horseshoe and .whenso attached will be firmly held therein during the process of heating said shoe and calk preliminary to the welding operation.

' The invention consists in a horseshoe-calk constructed with two attaching-prongs located upon opposite ends and upon diagonally opposite corners, respectively, of said calk.

' The invention again consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings, Figure 1 is a plan view of my horseshoe-calk. Fig. 2 is a rear elevatlon of the same. Flg. 3 1s an end elevvation as viewed from the left of Fig. 2. Fig.

4: is a plan view of ahorseshoe, illustrating my improved calk attached thereto. Fig. 5 is a section taken on line 5 5 of Fig. 4.

Like characters refer to like parts throughout the several views of the drawings.-

and 7 8 attaching-prongs integral therewith, said prongs being located one at each end of the body 6 and upon opposite sides; respectively, of a longitudinal median plane A A, extending through said calk. The prongs 7 and 8 are pointed and Wedge-shaped, the adjacent faces 9 and 10 thereof, respectively, being inclined away from each other and the outer faces 11 and 12 of the prongs 7 and 8, respectively, being each inclined inwardly from the faces 13 and 14, respectively, of'the body 6 of thecalk. The object of inclining the faces 11-and 12 inwardly from the faces 13 and 14 of the calk is to bring the points of the prongs 7 and 8 as far away from the edge of the horseshoe as possible to avoid splitting the same when thecalk is driven into the shoe,

it being desirable that thebody of the calk should be as near the edge of the shoe as possible. The object of inclining the faces 9 and 10 away from each other is to obtain a wedge-,

' shaped portion 15 of the horseshoe16 between the two attaching-prongs 7 and 8, as shown in Fig. 5.

It will be seen and understood that the prongs 7 and 8 are located at opposite ends of 1 the calk and upon diagonally opposite corners thereof, respectively, and that said prongs are swaged from the body of a rectangular blank, so that in manufacturing a rectangular blank of metal can be formed into a calk in accordance with my invention by swaging the prongs formed from a blank of rectangular material without any previous forming of said blank or of the rod from which it is cut. I

In dotted lines, Fig. 4e, a calk 17, formed in accordance with my invention, is illustrated as joining together the two heels or ends 18 and 19 of the horseshoe 16. n

The advantages secured by forming a calk as hereinbefore described are as follows: As

' well known to those skilled in the art, when In the drawings, 6 is the body of the calk,-

a calk is first attached to a horseshoe the shoe is heated to a cherry-red, and the attaching-prong of the calk is then driven into said shoe cold preparatory to being heated, together'with theshoe, to a welding heat. In attaching the calk to the shoe'in this manner the blacksmith holds the shoe with one pair of tongs, While the helper holds the calk in the proper position with another pair of tongs preparatory to having the prong upon; said calk driven into the shoe. It is desirable that the calk should -be attached to the shoe as near 7 the outer edge thereof as possible, and oftenthat the prong 8 will hold the calk to the shoe until it is welded thereto, because of the position of said calk, which is practically located midway between the inner and outer edges of the shoe. It will readily be seen also that in attaching the calk where there are two prongs said calk may be placed upon the shoe preparatory to being driven therein, resting upon said prongs much. the same as if it had an entire flat surface torest upon. The chief advantage, however, secured by my construction is that by the use of two prongs the calk is prevented from twisting and getting out of position and finally vfalling entirely out of the shoe when said shoe, with the calk attached thereto, is inserted in the fire preparatory to bringing the same to a welding heat. As calks are now constructed with one attaching-prong it very often happens that the calk drops out of the shoe or turns on the attaching-prong after the shoe has been pushed into the fire preparatory to obtaining the welding heat, causing much inconvenience, trouble, and loss of time to the blacksmith.

It will be seen and understood that the advantage secured by my construction of horseshoe-calk, in which the attaching-prongs 7 and 8 are provided with the adjacent edges 9 and 10 inclined away from each other, is that as the calkis being diven into the heated shoe, as hereinbefore described the farther the prongs are driven into the shoe, the more socurely will they become attached thereto on account of the wedge-shaped portion of the shoe lying between said inclined faces 9 and 10, said wedge-shaped portion 15 being forced in between said inclined faces.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is

1. As an article of manufacture, a horseshoe-calk constructed with two attachingprongs located at opposite ends and upon diagonally opposite corners, respectively, of said calk.

2. As an article of manufacture, a horseshoe-call: formed of a blank of rectangular cross-section and having two attaching-prongs swaged from the body of said blank and located at opposite ends and upon diagonally opposite corners, respectively, of said blank.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN H. VINTON.
